The Immense Benefits Of Central Air

  • Increased Comfort. This is one of the biggest benefits of central air conditioning. Window units usually have limited cooling capabilities and can only cool the immediate area where they are located—meaning you may need to purchase multiple window units (and spend more money). While window units only cool one area of the home, central air conditioning systems simultaneously cool the entire house.
  • Better Air Quality. Ahh… take a deep breath! Central air conditioning systems use filters which work to take pollutants, allergens, and the like out of the air, meaning fresher, cleaner air for you and your loved ones.
  • Low noise levels. One of the biggest pitfalls of traditional air conditioning systems is the noise level. Window units are located inside the house so they’re going to make noise—and depending on the system, this noise can be loud and potentially become a big annoyance. Central air conditioning systems, however, keep the condenser (and the noise!) outside of the house.

Does Your Central Air Need An Upgrade?

If you have an older central air conditioner, you might choose to replace the outdoor compressor with a modern, high-efficiency unit. If you do so, consult a Green Apple heating and cooling contractor to assure that the new compressor is properly matched to the indoor unit. However, considering recent changes in refrigerants and air conditioning designs, it might be wiser to replace the entire system.
Today’s best air conditioners use 30% to 50% less energy to produce the same amount of cooling as air conditioners made in the mid-1970s. Even if your air conditioner is only 10 years old, you may save 20% to 40% of your cooling energy costs by replacing it with a newer, more efficient model.
Proper sizing and installation are key elements in determining air conditioner efficiency. Too large a unit will not adequately remove humidity. Too small a unit will not be able to attain a comfortable temperature on the hottest days. Improper unit location, lack of insulation, and improper duct installation can greatly diminish efficiency.

Just One Of The Many Benefits Of Central Air

There are solid reasons why adding central air conditioning is the most viable option for bringing cool comfort to an existing home. Window units address comfort issues in single rooms or small enclosed areas only. In the midst of hot weather, residents find themselves increasingly restricted to these “islands” of coolness while the rest of the uncooled house remains stuck in the uncomfortable zone.
In addition, cooling individual rooms with multiple window units is more energy-expensive than running a single central air conditioner, particularly when you consider the substantial advances in efficiency available from new central systems today.
Aesthetics is another a drawback of window units. They’re bulky, block the outdoor view and reduce available light. Living with a noisy compressor and fan mounted in a window unit only a few feet from where you’re sitting or sleeping is never as quiet as a central system, where the loud components are exiled to remote locations like the attic and backyard.

Two Simple Ways To Prevent Heat Loss

2- Curtains are excellent for preventing heat loss. You can buy heavy-duty curtains, or thermal lining for your existing ones, for extra insulation. But try not to let your curtains hang over any radiators, as this can stop the heat from warming the room.
2- Insulating your home is one of the best ways to reduce your energy bills and make your house warmer and more comfortable. Warm air can escape from your home in all directions – including the roof, walls, floor, windows, and doors – meaning lots of the energy you pay for can go to waste.
If you don’t think your furnace is operating the way that it should be then please call your friends at Green Apple with any questions or concerns you might have regarding any of your HVAC or plumbing needs toll-free at 888-611-7191

Best Way To Protect Your Plumbing During The Winter

  • Green Apple recommends Insulating pipes in unheated areas, such as attics, crawl spaces and basements.
  • When below-freezing weather is forecast, open cupboard doors in the kitchen and bathrooms. This allows these pipes to get more heat from inside your home.
  • If you leave home for several days, put your furnace on a low setting. This may not prevent freezing pipes but it can help.
  • Let a slight drip of water run when temperatures dip below freezing. Use cold water to avoid water heating charges.

Why Is An Annual Furnace Inspection So Important?

Prevent problems with an annual inspection and maintenance visit.

Your furnace system controls the temperature and moves air throughout your home to keep it comfortable while also filtering out dust and allergens. A yearly preventative maintenance inspection by a qualified Green Apple Mechanical NJ service technician can keep your HVAC functioning at peak efficiency by identifying problems from thermal stress, movement, or dust. Common problems can be:

  • Duct work loosened due to normal thermal expansion and contraction;
  • Blower motor bearings in need of lubrication;
  • Replacing of air filter and cleaning of dust from blower fan blades and AC condensing coil.

An inspection can also find and repair less than obvious problems like:

  • Loose blower belt
  • Improperly firing burners
  • Blocked condensate drain
  • Loose wiring harnesses
  • Slowly leaking coolant from the AC system

The best way to keep your furnace efficient and reliable is to have it inspected before you really need it. Before cold weather strikes, set up an appointment to have your heating system inspected by an expert. Yearly fall maintenance can save you time, frustration, and money when it’s done right. Our technicians perform a comprehensive diagnostic check to ensure that your furnace is operating safely, efficiently and to manufacturer’s specifications.
From performing a safety test for carbon monoxide (CO) to checking the unit’s safe operating temperature, what’s most important is that when we leave your house we’re confident that we have done all of the checks to ensure your equipment is running safely and as efficiently as possible and to the specifications of the manufacturer.

What Can I Do Between Annual Maintenance Visits To Ensure My Furnace Continues to Run Efficiently?

Next to having your furnace checked annually by a Green Apple Mechanical NJ professional, changing your filter is the most important thing to do in between those visits to ensure your furnace and air conditioner? longevity and performance. One of the biggest culprits behind equipment issues are dirty filters which can:

  • Restrict airflow, which puts additional strain on the fan motor that after time can make your motor burn out, your system overheat or your equipment fail.
  • Force your fan motor to overwork which uses more energy, can cause damage to your system and significantly raise your utility bill.
  • Drastically reduce your indoor air quality which can aggravate allergies, asthma and other illnesses.
  • Clog ductwork with debris which can decrease your equipment’s life span and lead to costly repair or replacement expenses.

How often should I change my furnace filter?

Manufacturers typically recommend that furnace filters be changed every three months. However, we suggest you check your furnace filters on a monthly basis to see if they are filled with dirt and other debris. Homes with smokers or pets will likely need to change their filters more regularly than other households. So our advice is to be prepared to replace your furnace filter every 3 months, however, check the filter every month and replace more frequently if required.
Often a service technician can tell you common minor issues about your furnace make and model that you can solve yourself in the future. Plus, they’ll perform a multi-point safety check to verify your system’s safe operation.
A yearly maintenance inspection keeps your HVAC running like new and improves your energy savings. And by monitoring your HVAC’s performance and condition, you’ll enjoy its longer life and lower chances for an expensive break down.

One reason systems may appear not to be producing enough cold air is because of duct leakage. Duct leakage can sap 20 to 40% of the energy out of even a well-operating air conditioner, if the ducts pass outside the cooled space (this includes attics, crawlspaces and garages). Ducts outside need to be well insulated. Various products exist specifically for insulating ducts that can be installed by a keen home owner or a professional contractor.
You might be able to get an extra half ton of air conditioner capacity for free, if you seal your leaky ducts. If the ducts are accessible, handy consumers can seal ducts with mastic—that white sticky stuff you can paint on the ducts. Otherwise you would need a professional to seal the ducts.

How Much Does Air Conditioning Cost?

Most homeowners report spending between $3,699 and $7,153 to have air conditioning installed. This price is more typical of a central A/C unit installation rather than a window air conditioner addition which typically averages about $300. Your total cost for the job will depend on the type of system you choose.
The size of your home will determine the type of air conditioning system you will need.
There are several types of systems, including:

  • Window units: installed in windows as a singular unit
  • Split systems: either as mini-split (ductless) or central systems that are installed as inside and outside units
  • Central system: uses duct system that’s usually combined with the heating system to cool a whole house
  • Portable units: comes as a split, hose or evaporative system for ease of movement around the house
A window air conditioning unit will generally suffice to keep a smaller home cool on warm spring and summer days. The cost to install a window air conditioner averages between $150 and $300, depending on the size you need. Installing a window air conditioning unit can bring added comfort for a reasonable price, but it will be less powerful than a central air conditioning system.
If you have a bigger home with multiple rooms, you will probably need to have a central air conditioning system installed. Homeowners can pay between $500 and $4,000 for central air conditioning. The final cost will depend on the unit, additional installation items such as ductwork and the professional’s installation rates. Here are some additional factors that will determine the kind of system you will need, as well as its price.

Measuring Home Size in BTUs

The first major factor in determining what kind of air conditioning system you’ll need is the size of your home. Air conditioning units are measured in tons or the amount of heat they can remove from a home in one hour in British thermal units (BTUs)–more information on this measurement below. The larger your house, the more cooling power you’ll need. However, bigger isn’t better in every scenario. If the system is too large it will cycle on and off all the time, wasting energy and emitting a loud, disruptive sound. On the other hand, if the system is too small, it will run constantly and cool your house inefficiently.

New Air Conditioning Unit Load Calculation

An air conditioning contractor will do a load calculation to determine the proper air conditioning unit for your home. This calculation takes into account the climate, size, shape and orientation of your home, as well as its square footage. A professional will also look at the insulation, windows, walls, floors and other materials that compose your home. He will then examine any leaks, seals and existing ducts or vents. The general rule is that every 500 or 600 square feet requires one ton of cooling. However, this calculation varies from place to place and contractor to contractor.

Load calculating is often referred to as the Manual J methodology. Cooling professionals use a variety of computations to analyze your home’s heating and cooling characteristics, determining how much air it will lose. Factoring in environmental considerations like geography and solar rays, professionals can decide which system will best cool your home. There are two types of Manual J load calculations:

  • Whole House: Provides the air conditioning load calculations for a whole house with an existing duct system.
  • Room by Room: Used for calculating the air conditioning loads in every room of a house, which contributes to determining individual duct sizes and layout of a duct system

What are EER and SEER Ratings?

The best cooling unit for your home will be the most energy efficient and the least expensive to run. Air conditioning professionals help determine this factor in their load calculations, but the next step is looking at the energy efficiency ratio (EER) and seasonal energy efficiency ratio (SEER) ratings of cooling units. Here’s what you need to know about these two units of efficiency.

EER Ratings

An EER certifies the cooling efficiency of HVAC units. It’s calculated by the rate of the cooling in British thermal units (BTUs) per hour and divided by the rate of energy input in watts at a specific temperature. The calculation goes as BTUH/WATT at dry bulb (db) versus wet bulb (wb) temperatures. The optimal rating for a cooling unit is about 80db/67wb inside and 95db/75wb outside.

SEER Ratings

An air conditioning system’s SEER is especially important if you live in a climate that changes temperature dramatically. The SEER is determined by the cooling output during the winter divided by its electric input during the winter. The higher the SEER rating, the more efficient it will be. Cooling units specifically must have a minimum SEER of 13 as of January 2006, according to U.S. standards, so if you live in a home with a system installed before then, consider having it replaced. SEER 13 units increase home efficiency by 30 percent.
Once you’ve determined the size of the air conditioning unit you need, it’s time to look at different brands. Various manufacturers produce heating and cooling units, and there are pros and cons to each. Units also vary in cost, depending on bells and whistles. So, consult with a professional about what you need and ask about any additional features that may benefit your home. Here are some of the cooling unit manufacturers and their average costs (in alphabetical order):

  • Aire-Flo — $1,700
  • Amana — $2,600
  • American Standard — $3,200
  • Armstrong — $2,000
  • Bryant — $2,200
  • Carrier — $3,200
  • Coleman — $1,700
  • Comfortmaker — $1,700
  • Frigidaire — $2,900
  • Gibson — $2,300
  • Goodman — $2,100
  • Heil — $2,600
  • Lennox — $3,400
  • Payne — $1,400
  • Rheem — $2,500
  • Ruud — $2,400
  • Tempstar — $1,800
  • Trane — $3,300
  • Whirlpool — $1,900
  • York — $2,800

Installing the Air Conditioning Unit

It’s important to have made an informed decision about an air conditioning system before initiating an installation, as this will determine a large percentage of your cost. If you decide to have a split or central system installed, you will need to hire an air conditioning professional to install the system. You cannot do this installation as a DIY project because it involves handling refrigerant, which cools the air. Professionals must be licensed by the Environmental Protection Agency (EPA) before they can handle this substance because it’s a harmful chemical.

Installing an air conditioning system is an involved process. To that end, it requires the help of many professionals whose rates will drive up the cost. You will need at least:

  • Air conditioning contractor: he or she performs an assessment to determine what kind of system you need and installs it
  • Assistant(s): additional team that helps with the wiring, ductwork and metal bracket mounting
You will also be charged for the materials involved in the installation, including the air conditioning unit and chemicals. Check with your contractor to see whether you might cut costs by buying the air conditioning system yourself or using existing heating system ductwork in your home.

Additional Questions and Considerations

Do you already have a central heating system?

Many central air conditioning systems use the furnace blower to distribute cool air through the home. If you do not have a central heating system installed, it is cost-effective to install a heating and air conditioning (HVAC) system at the same time. If you already have central heat, you can use the existing fans and duct system for the central air system.

Do you need ductwork?

Although most new homes have ducts and vents already in place, many older homes have old convection heating systems or baseboard heaters without ductwork. In such cases, you will need to install ducts and vents to provide the air conditioning with a flow system. This would be the time to explore upgrading the existing heating system as well, as it will be much cheaper to do together.

How’s the insulation in your home?

If your home is well built and well insulated, your heating and cooling systems will work more efficiently and save you money. If you have poor insulation, you will spend considerably more on utility bills. Explore the costs of new insulation or upgrading your old insulation as it might save you money in the long run.
